A filter device 2 and a water storage tank 3 are fixedly mounted on the bottom plate 1. The water inlet end of the filter device 2 is connected to a pumping device 4. The water outlet end of the filter device 2 is connected to the water inlet end of the water storage tank 3. The water outlet end of the water storage tank 3 is connected to the water inlet of the sanitary unit body 6. The filter device 2 includes a filter box 21. A plurality of slots are provided on the inner wall of the filter box 21. Two coarse particle filter plates 22 and two reverse osmosis membranes 23 are slidably connected to the filter box 21 through the slots. The two coarse particle filter plates 22 and the two reverse osmosis membranes 23 are arranged in parallel inside the filter box 21.

[0025] When the sanitary unit main body 6 needs water supply, the pumping device 4 is first started to allow seawater to enter the interior of the filter device 2 through the pumping device 4. The coarse particle impurities in the seawater can be filtered through the coarse particle filter plate 22 in the filter device 2, and the salt in the seawater can be filtered through the reverse osmosis membrane 23. The filtered seawater enters the water storage tank 3 for storage and is supplied to the sanitary unit main body 6 for use through the water storage tank 3. A water heater is provided in the sanitary unit main body 6, and the water in the water storage tank 3 is supplied to the water heater through the water inlet. The water heater heats the water and supplies it to the shower device and the washing device. At the same time, by providing a slot on the inner wall of the filter box 21, the coarse particle filter plate 22 and the reverse osmosis membrane 23 can be detachably fixed in the filter box 21. When the coarse particle filter plate 22 or the reverse osmosis membrane 23 needs to be cleaned or replaced, they can be disassembled and installed in time and quickly to avoid damage to the coarse particle filter plate 22 or the reverse osmosis membrane 23 affecting the filtering effect.

[0026] For example 2, please refer to Figure 3 , a plurality of parallel arranged ultraviolet disinfection lamps 25 are fixedly connected to the bottom of the inner wall of the filter box 21, and the plurality of ultraviolet disinfection lamps 25 are located at the water outlet of the filter box 21, a suspended baffle 27 is provided between the reverse osmosis membrane 23 and the ultraviolet disinfection lamp 25, and the top of the baffle 27 is consistent with the top height of the filter box 21, a vacuum pump 28 is fixedly installed on the side wall of the water outlet side of the filter box 21, and the vacuum pump 28 is connected to the interior of the filter box 21, and two handles 24 are fixedly installed on the top of the two coarse particle filter plates 22 and the two reverse osmosis membranes 23;

[0027] By arranging the ultraviolet disinfection lamp 25, after the seawater passes through the coarse particle filter plate 22 and the reverse osmosis membrane 23, it is sterilized and disinfected by the ultraviolet disinfection lamp 25 to kill the microorganisms or bacteria in the seawater, so that the water entering the sanitary unit main body 6 is cleaner and safer to use. When the seawater enters the filter box 21, the vacuum pump 28 is started to extract the air near the water outlet end, so that the pressure at the water inlet end of the filter box 21 is higher than the pressure at the water outlet end. After the seawater enters the filter box 21, it will flow from the high-pressure area to the low-pressure area, so that the seawater can quickly and smoothly pass through the coarse particle filter plate 22 and the reverse osmosis membrane 23. By arranging a handle 24 on the top of the coarse particle filter plate 22 and the reverse osmosis membrane 23, when the coarse particle filter plate 22 and the reverse osmosis membrane 23 need to be cleaned or replaced, the coarse particle filter plate 22 and the reverse osmosis membrane 23 can be taken out through the handle 24, which is convenient and quick.

[0028] For example three, please refer to Figure 1 and Figure 3 The pumping device 4 includes a second water pump 41. The water inlet end of the second water pump 41 is connected to a pumping pipe 42, and the other end of the pumping pipe 42 is connected to the seawater. The water outlet end of the second water pump 41 is connected to a water supply pipe 43. The other end of the water supply pipe 43 is fixedly connected to a drainage box 44. The top of the drainage box 44 is fixedly connected to a mounting handle 45. The water supply pipe 43 is connected to the interior of the filter box 21, and the drainage box 44 is fixedly connected to the inner wall of the filter box 21.

[0029] When it is necessary to extract seawater, first turn on the second water pump 41, and the seawater is sucked by the second water pump 41 through the suction pipe 42 and the water supply pipe 43 to the inside of the filter box 21. By setting up a drainage box 44, before the seawater enters the filter box 21, it is first filtered through the drainage box 44 for larger impurities such as aquatic plants in the seawater. After the seawater is filtered in the filter box 21, the mounting handle 45 on the top of the drainage box 44 can be removed from the inside of the filter box 21 for cleaning to avoid blockage caused by excessive impurities in the drainage box 44.

[0030] For example 4, please refer to Figure 1 、 Figure 2 and Figure 3The water inlet end of the water tank 3 is connected with a water inlet pipe 32, a suction pump is provided in the water inlet pipe 32, the other end of the water inlet pipe 32 is connected to the filter box 21, a valve 33 is provided on the water inlet pipe 32, and the water outlet end of the water tank 3 is fixedly connected with a second pressure pump 34, and the second pressure pump 34 is connected to the water tank 3, the second pressure pump 34 is connected with a first water outlet pipe 35, the other end of the first water outlet pipe 35 is connected to the water inlet of the sanitary unit main body 6, and the water tank 3 is also provided with a transparent scale line 31 for observing the water amount in the water tank 3, a first water pump 36 is fixedly installed at the rear end of the water tank 3, and a first pressure pump 29 is fixedly installed at the rear end of the filter box 21, the rear end of the water tank 3 is connected with a second water outlet pipe 37 through the first water pump 36, and the other end of the second water outlet pipe 37 is connected to the interior of the filter box 21 through the first pressure pump 29;

[0031] When the seawater is filtered and disinfected in the filter box 21, the suction pump in the water inlet pipe 32 and the valve 33 on the water inlet pipe 32 are opened to allow the seawater to flow into the water storage tank 3 through the water inlet pipe 32 for storage. When water is needed in the sanitary unit, the second pressure pump 34 is turned on to supply the water in the water storage tank 3 to the sanitary unit through the first water outlet pipe 35. The water storage amount in the water storage tank 3 can be visually observed through the transparent scale line 31 on the surface of the water storage tank 3. When the water amount is less, the pumping device 4 and the filter device 2 are turned on again for filtering. After the filter device 2 has filtered the seawater, the first water pump 36 and the first pressure pump 29 are turned on to transport the clean water in the water storage tank 3 to the filter box 21 through the second water outlet pipe 37, and the coarse particle filter plate 22 and the reverse osmosis membrane 23 in the filter box 21 are rinsed and cleaned. After rinsing, the sewage is discharged. By providing the second water outlet pipe 37, the filter box 21 can be cleaned, making subsequent filtration smoother.

[0033] The water in the second water outlet pipe 37 can be flushed into the interior of the filter box 21 through the water outlet hole 26, and pressurized by the first pressure pump 29 to enhance the flushing effect. After flushing, the sewage is discharged through the drain port 7. By setting a handle 51, the cover 5 can be removed to facilitate the removal of the filtering and disinfecting device in the filter box 21.

[0034] The working principle of the utility model is as follows: by turning on the second pressure pump 34, the filtered seawater stored in the water tank 3 is supplied to the sanitary unit body 6 for use through the first water outlet pipe 35; when the water storage amount in the water tank 3 is observed to be less through the transparent scale line 31, the second water pump 41 is turned on to transport the seawater to the filter box 21 through the water pumping pipe 42 and the water supply pipe 43; the vacuum pump 28 on the filter box 21 is turned on to extract the air at the water outlet of the filter box 21, so that the seawater enters the filter box 21 and flows to the water outlet, and then flows through the drainage box 44. Large particles of impurities in the seawater are filtered, and the seawater after the initial filtration is filtered again through two layers of coarse particle filter plates 22 to filter the coarse particles, and the salt in the seawater is filtered through two layers of valves 33. After filtration, it flows to the water outlet end, and the ultraviolet disinfection lamp 25 is turned on to sterilize and disinfect the filtered seawater to further kill microorganisms and bacteria in the water. After the disinfection is completed, the suction pump in the water inlet pipe 32 and the valve 33 on the water inlet pipe 32 are turned on, so that the filtered water enters the water storage tank 3 through the water inlet pipe 32 for storage for next use;

[0035] After the filter box 21 has filtered the seawater, the first water pump 36 and the first pressure pump 29 are turned on to transport the water in the water storage tank 3 to the filter box 21 through the second outlet pipe 37 and flush out through the outlet hole 26 installed in the filter box 21 to clean the filter box 21. The cleaned sewage is discharged through the drain port 7. When the coarse particle filter plate 22 and the reverse osmosis membrane 23 need to be taken out for cleaning or replacement, the cover plate 5 is removed by the handle 51, and the coarse particle filter plate 22 and the reverse osmosis membrane 23 can be removed by the handle 24 installed on the coarse particle filter plate 22 and the reverse osmosis membrane 23. The coarse particle filter plate 22 and the reverse osmosis membrane 23 can be easily taken out from the filter box 21, and then the new coarse particle filter plate 22 and the reverse osmosis membrane 23 can be snapped into the slots on the filter box 21. The drainage box 44 can be taken out through the installation handle 45 on the drainage box 44 to clean the drainage box 44. By cleaning the drainage box 44, the filter box 21, the coarse particle filter plate 22 and the reverse osmosis membrane 23, the filtering effect is optimized each time, ensuring that the water entering the sanitary unit main body 6 remains clean and safe.
